Well here is one I managed to "dig up" from my storage shelf. Its the Lionel Texas Special Alco AA from 1958. It was new in '58 and lasted only one year. (IAW "Lionel Trains of the 1950's" by Classic Toy Trains) It pulled a six car freight outfit (#1599) . It included 2 new pieces of rolling stock: the 6464-60 Gulf 2 D tank car and the 6801-50 flatcar with a boat. The 6014 box car which could be either the reissued red Frisco or the new Bosco . The 6112 gondola with canisters, the 6424 flatcar with two automobiles and a 6017 SP type caboose. Despite offering 13 0-27 sets in 1958 including this one, it was a disappointing year. Sales were down and the founder, Joshua Lionel Cowen announced his pending retirement. Looking back, there is no question that the toy train golden years were coming to an end.
Here she is, the Lionel #210 Texas Special Alco AA from 1958:
Hope you have a great weekend. Stay hydrated and watch out for the heat.
